    Hi,

    I was trying to access one of EX4300 switch but unfortunately didn't get access from management IP/Console port. This switch suddenly stop the switch access but transit traffic is working fine. We rebooted the switch but no luck.
    Please suggest any way to get the switch configuration.

    Regards,
    Nik.

    Hi Nik,

    Hi HTH,
    Unfortunately I doesn't know the software version on the switch. It may be 15.3

    Regards,

    Hi Nik,

    The logs seen on the console are  fixed via below PR:

    Can you try to power cycle the switch again and see if you can access the switch after that.
